Grady Hillhouse is a professional civil engineer and hobbyist everything else in San Antonio, Texas. Randall Munroe said, "You can look at practically any part of anything manmade around you and think, Some engineer was frustrated while designing this. It's a little human connection." My goal for Practical Engineering is to increase exposure and interest in the field of engineering. I'm trying to highlight that connection between the world around us and the energy, passion, and thought that goes into making it a nicer place to live.

Hydraulic transients (also known as water hammer) can seem innocuous in a residential setting, but these spikes in pressure can cause major damage to large pipelines and industrial pipe networks. In this video, we briefly discuss how water hammer occurs and how engineers mitigate the effect.

There are a whole host of differences between modern concrete and that of the western Roman empire that I didn’t have time to go into, including freeze/thaw damage. This is such and interesting topic, so here are some references...

How Soil Destroys Buildings

Okay this is the last video on the hazards of soil mechanics for a while :) Support for this video comes from Brilliant: https://brilliant.org/PracticalEngineering/ Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.

The "quick condition" occurs when seepage reduces the effective stress of a soil. This can lead to some dangerous conditions, especially if the seepage causes piping erosion to occur at a dam.

Torque Converter, How does it work ?

Most of us enjoy the smooth and effortless feeling of driving in an automatic transmission car. The driving is effortless because you don’t need to worry about gear changing and you don’t have a clutch pedal to operate. In an automatic transmission car the work, of the clutch pedal, is automatically done by a hidden component, which is truly an engineering marvel, the torque converter. The torque converter can even multiply the torque. Let’s see how this purely mechanical device performs its tasks.

They are hard, tough, strong, and durable. As someone who occasionally works the wood, even I can admit that metals are a superior material in many regards. So you can see why it would be advantageous to have a way to connect them together, especially if...

What is Concrete?

What's the difference between concrete and cement?

How Water Towers Work

Purpose and function of elevated water storage tanks. Get some Bombas socks for 20% off! http://bit.ly/2PZuQLg Code: PRACTICAL The job of finding enough water, making it safe to use, and then reliably distributing it to the system customers with almost no downtime is a monumental task that requires a lot of infrastructure.

Horsepower vs Torque - A Simple Explanation

What's The Difference Between Horsepower & Torque? Why Is Peak Acceleration At Peak Power? https://youtu.be/cb6rIZfCuHI Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 Awesome Car Products: https://www.amazon.com/shop/engineeringexplained Which is better, horsepower or torque? Two words that are often stated in the car community, but often misunderstood. This video seeks to clarify the difference between the two, without silly analogies like "horsepower is how fast you hit the wall, torque is how far you take it with you" (which, by the way, is highly inaccurate). Torque is a force acting at a radius, while horsepower simply incorporates time into the equation. This video will discuss...

How to Make Free Energy Water Pump - Ram Pump

How to make a hydraulic ram pump which requires no electricity and no motor. NOTE : This pump uses falling water to lift a lesser amount of water to a higher elevation than the source. So, being primarily used for lifting relatively small amount of water to a higher elevation. if you want to deliver 2 cubic meter of water to an elevated location, you need at least 6 cubic meters of water to operate the pump 4 cubic meters of which will be used to drive the pump and goes directly as waste.

Why Concrete Needs Reinforcement

More destructive testing to answer your questions about concrete. The first 1000 people to click will get their first 2 months of Skillshare for free: http://skl.sh/PracticalEngineering2 Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement. -Patreon: http://patreon.com/PracticalEngineering -Website: http://practical.engineering This video was sponsored by Skillshare.

Sand Castle Holds Up A Car! - Mechanically Stabilized Earth

Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you'll see MSE walls are everywhere. Thanks for watching, and let me know what you think!

Signup for your FREE trial to The Great Courses Plus here: http://ow.ly/R5D730k3oNg The case of the Tacoma Narrows bridge is a well-known cautionary tale that’s discussed in engineering and physics classrooms across the world. Both resonance from vortex shedding and aeroelastic flutter contributed to the failure.
